Clare C. Yu is an American theoretical biophysicist and condensed matter physicist. She is Professor of Physics and Astronomy in the School of Physical Sciences at the University of California, Irvine (UCI). She is a Fellow of the American Physical Society, of the American Academy of Arts and Sciences, and of the American Association for the Advancement of Science. She is also a former Alfred P. Sloan Fellow,^[1] and a current Trustee of the Aspen Center for Physics.^[2][3]

Yu received both an A.B. (1979) and a Ph.D. (1984) in Physics at Princeton University. She conducted postdoctoral research at the University of Illinois at Urbana-Champaign and at the Los Alamos National Laboratory. In 1989, she joined the faculty at the University of California, Irvine.^[2][3][4]

Yu’s work encompasses three areas of study: biophysics, condensed matter physics, and quantum physics.

In biophysics, Yu studies the intracellular transport of molecules using computer simulations. In developmental biology, she has used Monte Carlo simulations, particularly to investigate the development of the wing disc in Drosophila fruit flies and to study how, fundamentally, the organs and physical features of creatures emerge. Additionally, she has deployed statistical techniques like maximum entropy to study cancer immunotherapy, uncovering under what conditions immune cells infiltrate tumors.

In condensed matter physics, Yu specializes in disordered systems. Focusing especially on glasses, she has researched the glass transition, Coulomb glasses, dipolar glasses, spin glasses, and the low temperature properties of glasses.

Yu’s research in the field of quantum computation has explored how fluctuating electronic spins on the surface of Josephson junction qubits can produce magnetic noise, leading to decoherence of the qubit.^[2][5][6]
